The core committee has agreed that it's about time for a new set of
update releases (8.1.3, 8.0.7, etc). Barring surprises, we'll wrap
Sunday evening with expectation of general announcement Tuesday.
Any pending patches out there for the back branches?

I'd really like to see the multiple DB connections with different
Kerberos credentials go in to 8.1.3. It solved the problem we were
having authenticating to PostgreSQL using Kerberos from Apache. We were
also able to get phppgadmin to use Kerberos authentication with this
patch (which is very nice). That patch also went into the 8.1.2-2
release of the Debian packages (along with the pg_restore patch which
was already committed to CVS). Havn't heard of any problems with it so
far, though 8.1.2-2 only hit the Debian mirrors yesterday.
Thanks!
Stephen

So Debian has a patch that is not in 8.1.2? I can't believe that they
are doing that -- personally I'm against to add any patch into binaries
that is not in the core.

That's a new feature, not a bug fix. I'd be against back-patching it
even if it had been in HEAD long enough to get some meaningful amount
of testing ... and since it's not even in HEAD yet ...

It's a bug. PostgreSQL properly supports using different authentication
credentials across seperate pg_connect()'s for all of the other
authentication types. The only reason it doesn't for Kerberos is because
of improper use of static variables which aren't reset between the
authentication requests. The patch fixes this and cleans up the
static variable handling.
Thanks,
Stephen

I still think this should be applied to back branches. The patches queue
is really quite a bit behind.

I'm not sure they do but they're not really a fair comparison as they
have a somewhat privileged position due to Tom (not that I'm
complaining, honestly I think it's wonderful that RH has an apparently
dedicated person for Postgres and it's outstanding that it's someone as
intelligent and knowledgable as Tom). It's certainly not uncommon for
distributions in general to patch programs which make them not-quite
pure upstream. Then again, just a recompile can break things too so
it's not like pristine source is always an option. It's also true, as
has been pointed out before, that Debian uses --enable-integer-datetimes
(or whatever the flag is) which isn't enabled by default. For the vast
majority of Debian users this is correct and better than the default but
it does mean that a PostgreSQL default-options compile will generate a
postmaster that can't work with Debian data files. Then again, if you
omit --enable-krb5 and the Debian package doesn't then if you move to a
default-compiled version you might not be able to authenticate to your
database anymore either.

Debian had the patch to enable ident over unix domain sockets well
before core did. So long that I didn't even realise it was a patch
until I compiled my own version. The patch had been submitted upstream
but fell between the cracks. As a Debian user it something I like.
The changelog entry says:
* Add debian/patches/12-krb5-multiusers.patch:
- Fix krb5 credential handling in libpq for multiple connections with
different users: Don't keep credentials in global variables, but pass
them around in a new krb5_info struct.
- Patch from Stephen Frost, proposed to be adopted upstream.
I consider it a form of preventative bug fixing. Somebody on Debian is
bound to complain about it sooner or later, so may as well fix it now.
There is a group who likes having kerberos working properly...
I imagine if a similar bug affected SSL connections, people would be
jumping up and down to have it fixed.
Have a nice day,

As against which, you have to consider the probability that the Debian
patch breaks something. With a maintainer who is not one of the main PG
developers accepting patches that haven't yet been reviewed (much less
beta-tested) by the community, that risk seems far from negligible.
(Now Red Hat certainly also puts in patches that aren't yet released
upstream, but we try to avoid getting ahead of upstream patch development.)

Heh don't log into #postgresql then - we have all pretty much been

I think the other important thing to consider is that this patch went
into debian's unstable branch, not stable.

Oh, pah, I'm there already, as 'Snow-Man' and I've heard all about it.
Sorry that Debian/stable releases havn't been coming out as frequently
as they really should have been. We're working on that, honest!

While I appriciate the core developer's expertise I don't think lack of
being a core member alone makes Martin's critique of the patch somehow
less valuable. I've also posted the patch to both -hackers and -patches
and I'd love for the community to review it.
And, to be fair, it's going into Debian/unstable and won't be in a
stable release without further testing by the Debian/unstable users
and Debian/testing users (once it propagates there). Unless there are
serious problems with it though I expect it to be in the next stable
Debian release (currently slated for the fall, iirc). It wouldn't go
into an update to the current Debian/stable as it's not a security fix.
I'm still very much of the opinion it's a bug and it's not terribly
complicated of a fix when you look at it. The patch looks bigger than
the actual change really is because of the structure references. Those
pieces aren't actually changed beyond referencing the structure variable
instead of the static variable though.
> (Now Red Hat certainly also puts in patches that aren't yet released

Debian in general doesn't like to differ much from upstream and so it
would certainly be nice to have the patch accepted into *some* point
release which could be included in the next stable Debian release. It
seems unlikely 8.2 will be out with enough time for it go through
Debian's testing before the next stable Debian release.

Stephen

Yes, it is, no question. I am working on the INET + INT patch now.

You haven't been looking too closely at the way some distributions are
building their packages then. At least two of the distributions I use
regularly (Gentoo and Debian) have the habit of adding a load of patches
during package build. And not all of those go back to the upstream, to

And they are not always sensible. A while back the Gentoo packagers
decided to "improve" the messages from initdb - the patch they applied
was completely erroneous, and I believe they have now fixed it.
I tend to be suspicious of distro applied patches. (I do like the change
to use log rotation that recent Rh/Fedora packages have made.)

The only thing that I hate is that libpq defaults to searching the
local socket in /var/postgresql/ or thereabouts. It really drives me
crazy and I've banned the libpq packages from my system.

Where the upstream package puts it, /tmp ... But yeah, I know about the

Maybe this should be a configure flag, just like the port number is.

It is ... that isn't the issue, the problem is exactly that Debian
chooses to exercise the option to make their installations different
from everyone else's.

FWIW, I prefer the Debian location. AFAICS the only rationale for
putting it in /tmp is "because it's always been there". I also agree
with suggestions to move ssh and X11 sockets out of /tmp. /tmp should
be for, well, temporary files...

Actually, it's "because it's certain to be there and be accessible to
unprivileged users". If we tried to change to something like
/var/postgresql, then getting that directory made and properly
permissioned would be an additional installation-time stumbling block
in the way of newbies. That's not an issue for prepackaged builds that
(at some level) require root privs to install, but I don't foresee it
becoming the default for builds from source. Especially not given the
client/server compatibility problems it'd create.

It is exatly distributor's job to give consistent system. I would
not like to use a distro that just does './configure;make;make install'
without any overview.
Especially considering that upstream defaults are bad.
OTOH as upstream job is _not_ to care about consistent system
- as it is not possible - then for upstream the backwards compatibility
is the most important thing. It is likely that PostgreSQL upstream can
move the default only when most distros have already changed to sane
setting.
Oh, and I personally like that self-compiled PostgreSQL defaults to
other locations than system one. Lessens danger of using experimental
stuff on useful data.

Isn't this a bit problematic because any local user can impersonate a
PostgreSQL backend which has been shut down?

Well, I guess it's an issue. At least it's not suceptable to the
standard symlink attacks. There is in general no way of knowing if the
server you are connecting to is what you think it is (except via SSL
maybe?).
The good thing is that if you're using md5 auth they can't grab your
password. The bad thing is that the server decides the authentication
protocol :(. Man-in-the-middle attacks would only be feasable for
attacker that have the same UID as the postmaster (deleting the socket
and creating a new one over the top). In those cases there's little you
can do anyway.
Putting the socket in a directory owned by the postgres user does stop
other users impersonating the server. Currently, if two local users
both compile a postgres server, they may end up connecting to
eachothers servers :).
These no real way around this. The only real option would be moving to
a home directory but that would require knowing the username the server
is running under...
Have a nice day,

And the problem would still exist, with even less chance of solution,
for TCP connections which are probably the majority of real-world usage.
If you're concerned about this sort of attack I think it has to be
solved in the protocol, not by reliance on socket placement.
I'm not sure whether our current SSL support does a good job of this
--- I think it only tries to check whether the server presents a
valid certificate, not which cert it is. Possibly Kerberos does more,
but I dunno a thing about that...

For local (i.e. UNIX domain socket) connections, there is -- just use
a hard-coded path where each directory is only writable by root or by
the PostgreSQL superuser (/var/run in Debian is not world-writable,
for instance).

The password is probably of little concern if you use UNIX domain
sockets. But feeding wrong data to the application might trigger
interesting things.

With AP_OPTS_MUTUAL_REQUIRED (which we and most other Kerberos
client/server setups use), the user and the server authenticate to each
other. The server has to prove it has access to the same key the KDC
has on file for the server, and the client has to do the same. We
really should support the various options for SSL checking. Options to
define trusted CAs, checking CN against what the IP address of the
server resolves to, mapping of DN to username (perhaps regexp based),
explicitly certificate -> username mapping, etc...
Of course, it'd be nice to get SASL support and move to GSSAPI instead
of the Kerberos API... :)
Thanks,
Stephen
